Changes in lung function tests in patients with bronchial asthma in response to 60 degree upright tilting

الملخص EN

This study was carried out to investigate the effect of 60° upright tilting on lung function test in patients with bronchial asthma. A-Effect of changing of posture to 60°upright tilting on normal (control) subjects indicates that the FVC, FEV1 & PEFR were significantly higher in 60°upright tilting than that of supine values and no significant difference in FEV1 %, and the differences between supine and 60°upright tilting values of FVC, FEV1 & PEFR were significantly higher in asthmatic patients with no significant change in FEV1 %. B- Effect of changing of posture to 60° upright tilting on all the asthmatic patients indicates that the FVC, FEV1 & PEFR were significantly higher in 60°upright tilting than that of supine values, while there was no significant changes in FEV1 %. C- The effect of changing of posture to 60°upright tilting in both age groups i.e. group 1 (20-39 year) and group 2 (40-60 year) indicates that there was significant increase in FVC, FEV1 and PEFR in 60° upright tilting with no significant change in FEV1 %. On comparison between group1 & group2 in supine & 60° upright tilting FVC, FEV1 FEV1 % were significantly higher in group1 than group2 but no significant difference was found in PEFR between group1 & group2 in both supine and 60° upright tilting. D-The difference between the normal control subjects in this study and that of predicted values in both male and female of FVC, FEV1, and PEFR indicate that the predicted value in both male and female is slightly higher than that of the control values.
